Hybrid-Electric VTOL Aircraft

Micor | Advanced Multi-Passenger VTOL Aircraft
Hybrid-Electric VTOL Aircraft
One of Micor Technologies’ main activity trust is the development and application of hybrid-electric propulsion for ground and aerial vehicles based on a unique multi-fuel Wankel engine range extender technology. For aircraft application the range extender working in tandem with an energy storage unit such as a battery pack or a fuel cell is the power source while high power density electrical motors are activating the propelling units such as ducted- fans, tractor or rotor propellers. These are the key components of the emerging Distributed Electric Power (DEP) for aircraft propulsion. The DEP system facilitates, in turn, the design of very innovative Vertical Take-off and Landing (VTOL) aircrafts.

Advanced Multi-passenger VTOL Aircraft (AMVA)

AMVA variant shown here is an aerial vehicle for 5 to 7 passengers with a seamless transition from take-off to forward flight phases. The aircraft tilting body keeps the pilot and the passengers in an optimal position during all flight phases. AMVA propulsion can be achieved with open rotors or with ducted fans.


Advanced Individual VTOL Aircraft (AIVA)

AIVA is an individual aerial vehicle with a tilting body which keeps the pilot seat in optimal position during the take-off position and in forward flight phases.

Some of the advantages of the AMVA and AIVA tilting body VTOL aircrafts:

  • The control of the vehicle is made by thrust differentiation, without pivoting propellers, wings or flaps
  • The aircraft construction is simple and cost effective
  • Reduced maintenance cost
  • Same propulsion system is used for vertical flight as well as for forward flight
  • It uses a thrust augmentation arrangement to increase the lift even in static conditions, resulting an unitary or a sub unitary thrust/weight ratio
  • In forward flight the lift is produced by the wings
  • It is a highly efficient vehicle in both vertical and forward flight with improved range
  • The propellers are protected against the contact with environment or with the personnel on the ground
  • It has a high redundancy level by using multiple thrust producing elements
  • Very compact vehicle which uses the entire wingspan to produce lift
  • It has amphibious capability
  • It can also use wing-in-ground (WIG) effect which reduces the lift-dependent drag

View the AMVA and AIVA slide shows for more information on these VTOL designs.

A short video featuring the AMVA aircraft can be viewed in our video section HERE.


Variable Geometry VTOL aircraft (VAGEV)

VAGEV is an extremely compact VTOL concept creating thrust augmentation effects in vertical flight in order to reduce the size and the weight of the required power source. The VAGEV’s take-off and forward flight phases are shown here:

The key benefits of the Micor’s VAGEV technology are:

  • Improved maneuverability during VTOL and hover, including in high wind conditions
  • Increased flight range due to the high lift/drag ratio
  • Smooth transitions at all stages between VTOL and forward flight
  • Increased hover efficiency combined with reduced disk loading
  • Extremely compact size during VTOL operation in the air and on the ground (a 2-passenger vehicle having a just 4x 4.4 m foot print)
  • Increased payload capacities
  • Protected rotors against the contact with the environment and surrounding personnel on the ground

This VAGEV vehicle’s external dimensions for 2 passenger variants are shown here:
